Stores the critical data of a distributed system as keys and values, with Raft consensus, a gRPC API and automatic TLS. For engineers who build or run clusters such as Kubernetes. etcd is an open-source project on GitHub in the Developer category, listed by Mindket. It is free. This is version 1, last updated on 2026-11-12. Install it from GitHub as its README says. Get Mindket’s setup notes on your Mindket account, as a zip. Made by etcd-io ## About ### What it is etcd is a distributed key-value store for the most important data of a distributed system. Go is its language, and Raft is the consensus algorithm behind its replicated log. ### Who it suits etcd suits engineers who build or run distributed systems and need a store that every node can agree on, such as platform teams and backend developers. | Industry | Who uses it | How they use it | Example | | --- | --- | --- | --- | | Cloud platforms | Platform engineers | Keep shared cluster state in a replicated store | Storing configuration that every node in a cluster must agree on | | Container orchestration | Kubernetes operators | Run it as the store beside Kubernetes | Keeping a cluster's core data in etcd | | Software development | Backend developers | Read and write keys through the gRPC API | Reading a shared setting from several services | | Distributed systems | Infrastructure teams | Rely on Raft for agreement between nodes | Deciding which node holds a role at a given time | Anyone who only needs a local settings file or a cache for one app can skip it. ### Where to use it etcd serves distributed systems and is often teamed with other software. - Clusters of machines that share critical data - Kubernetes, which the project names as a frequent partner - Other tools the notes name: locksmith, vulcand and Doorman - Your own applications, through the gRPC API | Use case | Who | What they get back | | --- | --- | --- | | Shared configuration | Platform teams | One store that all nodes read from | | Cluster coordination | Infrastructure engineers | Agreement across nodes through Raft consensus | | Application data | Developers | Keys and values through a well-defined API | ### How to set it up The README warns that the main branch may be unstable or broken while development goes on. Choose a release for stable use. 1. Open the project's releases page and pick a stable version. 2. Copy the code with git from the GitHub page if you want the main branch instead. 3. Follow the setup in the project's README. Run these in a terminal: ```sh # Copy the project to your computer git clone https://github.com/etcd-io/etcd.git # Go into its folder cd etcd ``` ### How to use it Your programs talk to etcd through its gRPC API. The project describes four aims: - Simple: the user-facing API is gRPC and well defined - Secure: TLS is automatic, and client certificate authentication is optional - Fast: benchmarked at 10,000 writes a second - Reliable: Raft keeps it properly distributed ### Example A platform team stores its cluster's critical state in etcd. The nodes agree on each change through Raft, and clients reach it over gRPC with TLS. ### For newcomers and experts etcd is a small database for the settings and facts that a group of computers must agree on. It stores each piece of data as a key with a value. A first small thing to try is storing one setting and reading it back through the API. The design puts a well-defined gRPC API in front of a Raft replicated log. Its topics tie it to the CNCF, Kubernetes and distributed databases, and it is written in Go. A client calls the gRPC API over TLS → The members agree on the change through Raft → The change enters the replicated log → The key and its value are stored ### Good to know This kit holds notes and a pointer to the code, so nothing runs by itself. - License: Apache-2.0 - Cost to run: none named - Data it reaches: whatever keys and values your systems store in it - Not for: running the main branch where stability matters, since it may be unstable or even broken during development ## README ````markdown # etcd Stores the critical data of a distributed system as keys and values, with Raft consensus, a gRPC API and automatic TLS.
